They’re made from A356-T61 aluminum, making them as strong as the original castings, but much lighter. The intake runners have been optimized to increase flow velocity and Trick Flow uses a special CNC Street Ported treatment to ensure proper dimensional accuracy and balance between the runners.

You can get these cylinder heads fully assembled (as shown), or as a bare casting if you’d like to do any port work or build your own valvetrain. (Image/Summit Racing)

The fine folks at Car Craft used these heads on a 482 c.i.d. Ford FE-series engine build. With the help of some other upgrades, the PowerPort® 175 Cylinder Heads helped the engine create more than 700 horsepower on the dyno.
